CAPSULE FOR COMPRESSED OR LIQUEFIED GASES.

SPEGIFIGATION forming part of Letters Patent No. 640,207, dated. January 2, 1900.

Application filed October 9, 1899. Serial No. 733,096. (No model.)

- To all whom it may concern:

Be it known that I, HEINRICH Konnonr, a citizen of Switzerland, residing-at 6 Archivstrasse, Berne, Switzerland, have invented certain new and useful Improvements in Gapsules for Corn pressed or Liquefied Gases, (patents applied for in Germany, February 23, 1899, and in Switzerland March 13, 1899;) and I do hereby declare the-following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the 1 same.

' by means of the turned-in edge of the capsule Figure 1 represents a longitudinal central section of a capsule embodying my invention; Fig. 2, a similar view of a somewhat-modified form of such capsule.

The capsule a in Fig. 1 has an outer cover I), preferably made of some hard metal-for example, of metal similar to the capsule itselfand provided with central collar b and an inner cover c, made of some soft material-such as sheet tin, sheet aluminium, or the like. Both covers are tightly pressed neck against the inner shoulder 11 of such neck, the inner soft cover 0 serving at the same time as a means of tightening. In a recess of the outer cover I) a suitably-formed perforator e is arranged, the stem of which engages or fits in the collar b of the outer cover and projects therefrom, so that by means of pressure or of a blow applied tothestem the perforator e is caused to penetrate the innor soft cover 0 of the capsule a, whereby the lowing:

and outer cover.

gas is enabled to pass through the hole thus formed.' In order to facilitate the escape of -thegas through the outer cover I), the same is vented, for which purpose small outlets f are provided, or the hole in which the stem 6 is guided is made sufliciently wide for the purpose. In the form represented in Fig. 2 a further cover 9, made of some hard material, is placed below the soft inner cover 0 and has a small hole h, which regulates the outflow of the gases after the soft cover 0 has been perforated.

What I claim, and desire to secure by Lot ters Patent of the United States, is the fol 1. A capsule for compressed or liquefied gases comprising an inner cover and an outer vented cover in combination with a perfo rator movably mounted between the inner 2.' A capsule for compressed or liquefied gases comprising an inner cover and an outer vented cover provided with a collar in combination with a perforator whose stem loosely engages the collar in the outer cover and projects beyond the same. I

3. A capsule for compressed or liquefied gases provided with an inner shoulder and a turned-in edge or flange in combination with an inner and an. outer cover clamped between the shoulder and turned-in edge, and a perforator movably mounted in the outer cover.

4. Improvements in capsules for compressed or liquefied gases consisting of an innor soft-metal cover and an outer cover, and a perforator arranged between the inner and outer cover for the purpose of perforating the first-named cover, the stem of said perforator being guided in the outer cover and projecting therefrom, for the purpose ofefiecting a per foration of the soft cover to permit the exit of the gases by means of pressure or of a blow applied to such stem.

In testimony whereof I aflix my signature in presence of two witnesses.

HEINRICH KORRODI. Witnesses:
